John invests $6750 in an account that pays 6.25% interest per year. After how many years will her
investment be worth $20,000? Show your work.
A = Pert
Answers
Answer:
32 years
Step-by-step explanation:
fist find how much of 6750 is 6.25%
6750 * .0625 = 421.875
then use trial and error until u get the number u want
421.875 * 10 = 4218.75 + 6750 = 1096875 NO
421.875 * 20 = 84375 + 6750 = 151875 NO
421.875 * 30 = 12656.25 + 6750 = 19406.25 NO
421.875 * 31 = 13078.125 + 6750 = 19828.125 NO
421.875 * 32 = 13500 + 6750 = 20250 YES

5C. Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?
Answers
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda still have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer:
20

Suppose demand d for a company's product at cost x is predicted by the
function d(x)=0.36x + 810, and that the price p that the company can charge
for the product is given by p(x) = x+14. Find the company's revenue function.
Answers
Answer:
0.36x ² + 815.04x + 11,340
Step-by-step explanation:
Revenue = price × quantity
p(x) = x+14
d(x) = 0.36x + 810
Revenue = price × quantity
= (x + 14) * (0.36x + 810)
= 0.36x² + 810x + 5.04x + 11,340
= 0.36x ² + 815.04x + 11,340
Company's revenue = 0.36x ² + 815.04x + 11,340
A cube-shaped box has a volume of 27 cubic inches. If the box is packed full of cubes with edge lengths of 1 inch, how many cubes can fit along one side of the
box?
Answers
Answer:
9 along one side.
Step-by-step explanation:
This question may be a bit tricky.
The side should mean the entire side, not just along the bottom edge.
The bottom row will have three 1-inch cubes. Three more in a middle row, and three more on top of that. That is a total of nine on that side.

Answers
Answer:
a) The dimensions of the garden are: 4.5 ft and 5 ft
b) 22.5 ft² of fencing material
c) The most precise name for the shape of the garden is a Rectangle
Step-by-step explanation:
a) Jenna has a garden with coordinate A(2,-1), B(4,3), C(9,3), D(7,-1) where each unit is 1 foot.
What are the dimensions of the garden rounded to the nearest 10th? (Looking for the lengths of the sides)
When we are given coordinates, we find the dimensions using the formula
= √(x2 - x1)² - (y2 - y1)²
(x1 , y1) and (x2 - y2)
For side AB
A(2,-1), B(4,3)
= √(4 - 2)² + (3 - (-1))²
= √2² + 4²
= √4 + 16
= √20 units = √20 feet
= 4.472135955 feet
Approximately = 4.5 feet
For side BC
B(4,3), C(9,3)
= √(9 - 4)² + (3 - 3)²
= √5² + 0²
= √25
= 5 units = 5 feet
For side CD
C(9,3), D(7,-1)
= √(7 - 9)² + (-1 - 3)²
= √(-2)² + -4²
= √4 + 16
= √20 units = √20 feet
= 4.472135955 feet
Approximately = 4.5 feet
For side AD
A(2,-1), D(7,-1)
= √(7 - 2)² + (-1 - (-1))²
= √5² + (-1 + 1)²
= √5² + 0²
= √25
= 5 units = 5 feet
Therefore, the dimensions of the garden are: 4.5ft and 5 ft
b) If Jenna decides to buy fencing for the garden, how much fence material does she need to buy? (Free response)
To buy fencing material for the garden, we have to find the area of the garden
Formula = Length × Width
= 4.5 ft × 5 ft
= 22.5 ft²
Therefore, Jenna needs to buy 22.5 square feet of fencing material.
c) What is the most precise name for the shape of the garden?
From the above calculation, we can see that
Side AB = Side CD = 4.5 ft
Side BC = Side AD = 5 ft
Therefore, the most precise name for the shape of the garden is a Rectangle
During swim practice, an Olympic swimmer is required to complete three swimming intervals, in this order: warm-up freestyle, sprint freestyle, and cool-down breast stroke. After he completes each interval, he rests for three minutes.
Sketch a graph that represents the swimmers’ interval times with respect to swimming speed. Assign the x- and y-axes with appropriate labels. You may use description words instead of numbers to label the graph.
Answers
Answer:
I'm not sure if the warm up speed is less than the cool down speed. If it is different than how I did it you just need to swap their positions on the y axis, so the "lumps" or whatever you want to call the shapes will be in opposite positions. The middle one will stay the same because it is the fastest and in between the two happening. Also let me know if you can't read any of the labels

Area of a triangle is given by
[tex]A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}[/tex]

A population of wolves in a county is represented by the
equation P(t) = 80(0.98)', where t is the number of years
since 1998. What is the percent decrease of wolves per year?
Answers
Answer:
P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998 Step-by-step explanation:
P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998
The percent decrease of wolves per year is 2%.
To understand more, check below explanation.
Percentage decrease :A population of wolves in a county is represented by the equation,
[tex]P(t)=80(0.98)^{t}[/tex]
where t is the number of years.
Let us consider that, 1998 is base year. so that, t = 0
[tex]P(0)=80[/tex]
Population of wolves in 1999, substitute t=1
[tex]P(1)=80*0.98=78.4[/tex]
the percent decrease of wolves per year is computed as;
[tex]=\frac{80-78.4}{80} *100\\\\=\frac{1.6}{100}*100\\ \\=0.02*100=2\%[/tex]
The percent decrease of wolves per year is 2%.
